rpl_semi_sync_master_enabled ON
rpl_semi_sync_master_timeout 10000
rpl_semi_sync_master_wait_point AFTER_COMMIT
rpl_semi_sync_slave_enabled ON


on master:  SHOW GLOBAL STATUS LIKE '%semi%' ;
*Rpl_semi_sync_master_clients 1   #  should show : 2 *
 ......

on slave1:   stop slave io_thread;
 then on master: SHOW GLOBAL STATUS LIKE '%semi%' ;
*Rpl_semi_sync_master_clients ０*

on slave1:   start slave io_thread;
on master:  SHOW GLOBAL STATUS LIKE '%semi%' ;
*Rpl_semi_sync_master_clients 1*


on slave2:   stop slave io_thread;
 then on master: SHOW GLOBAL STATUS LIKE '%semi%' ;
*Rpl_semi_sync_master_clients ０*

on slave2:   start slave io_thread;
